The objective ofthis study, was to investigate the mechanical, adhesion and corrosion properties with different graphene loading (0%, 1%, 3% and 5%) filled in unsaturated polyester and to determine the self healing properties via microcapsules on the unsaturated polyester-graphene coating for primer coating application with different microcapsules loading (1, 3 and 5wt%).
